AI Verdict
This is a 1000W, 80+ Gold, fully modular ATX 3.1 and PCIe 5.1 power supply with dual 12V-2x6 cables, built for current and next-gen high-power GPUs.
This 1000W, 80+ Gold power supply is a strong fit for modern gaming systems, especially those with NVIDIA's upcoming RTX 50 series GPUs, due to its ATX 3.1 and PCIe 5.1 readiness and dual 12V-2x6 connectors. Its compact 150mm length also makes it suitable for a wider range of ATX cases.
If you're building a system with a high-end AMD GPU that relies heavily on traditional 8-pin PCIe connectors, look for a PSU explicitly listing a higher count of native 6+2 pin connectors.

- May not provide sufficient traditional PCIe 8-pin connectors for some high-end AMD GPU configurations, potentially requiring adapters.
- While cables are described as 'nice' and 'individually sleeved' by some users, others suggest they might not be as premium as those from some competitors like Super Flower.
Dimension Scores
The 80 Plus Gold and Cybenetics Gold certifications indicate high power efficiency, and 1000W is ample for most high-end gaming systems.
While advertised as low-noise with a Zero Fan Mode, a user reported fan audibility at idle, suggesting it might not be completely silent for all users.
The inclusion of 100% server-grade 105°C Japanese capacitors and a 10-year warranty points to a focus on component quality and longevity.
Being fully modular with embossed jacket cables that are described as 'nice' and 'more bending' by users, it offers good flexibility for routing and a clean build.
Best For
- Gaming PCs utilizing NVIDIA RTX 50 series graphics cards or other PCIe 5.1 GPUs requiring dual 12V-2x6 power.
- New PC builds or upgrades aiming for ATX 3.1 compatibility and future-proofing for power excursions.
- Compact ATX cases where a 150mm PSU length is beneficial for space and cable routing.
Not Recommended For
- Systems with high-end AMD GPUs that require multiple traditional 8-pin PCIe connectors without relying on adapters.
- Users who require absolute silence from their power supply, as some reports indicate fan audibility at idle.
Watch Out For
- The fan might be audible even at idle, which could be a distraction for users expecting silent operation from the 'low-noise' and 'Zero Fan Mode' features.
- If you're running a high-end AMD GPU that needs multiple 8-pin PCIe connectors, you might find the native supply limited, potentially needing an adapter or different PSU altogether.
- While the cables are fully modular and embossed, some users perceive them as less premium than those offered by certain competitors, which could affect aesthetics or flexibility in tight builds.

What Buyers Say
The standout feature for many users is its readiness for next-gen GPUs, specifically with the dual 12V-2x6 connectors for PCIe 5.1 graphics cards. People also appreciate the fully modular design and the quality of the included cables, often describing them as 'nice' and easy to work with. However, there's a split on noise, with some finding it silent and others reporting the fan is audible even when the system is not under load. The compact 150mm length is a definite plus for fitting into various cases.
“Got this for my new 5080, cables are actually pretty sweet and it fit in my smaller case, but man, I can hear that fan sometimes even when I'm just browsing, kinda annoying when they say 'low-noise'.”
Common Praise
- Includes dual native 12V-2x6 cables for direct connection to PCIe 5.1 GPUs.
- The fully modular design simplifies cable routing and reduces clutter inside the PC case.
- Cables are described as 'really nice' and 'higher quality' by users, with some noting they are individually sleeved and come with combs.
- Its compact 150mm length is convenient for installation in smaller ATX cases.
- Offers a 10-year warranty, providing long-term peace of mind.
Common Complaints
- The fan can be heard at idle in all three modes, which is a letdown for those expecting completely silent operation.
- Some users found the number of traditional 8-pin PCIe connectors insufficient for certain high-end AMD GPU setups.
- The overall value proposition was questioned by one user, feeling it wasn't 'as excellent as a PSU for its price should be'.
Ownership Tips
- The dual 12V-2x6 cables are a game-changer for new GPU installations, no more clunky adapters for the latest cards.
- The 150mm depth really helps with front-to-back airflow in some cases, making cable management behind the PSU easier.
- Even with 'Zero Fan Mode,' the fan might kick in and be noticeable under light loads or even idle, so don't expect absolute silence all the time.
- The embossed jacket cables, while flexible, might still require some effort to bend sharply in very tight spaces.
Frequently Asked Questions
Does this PSU come with the new 12V-2x6 power cables?
Yes, it includes dual native 12V-2x6 connectors, designed to power PCIe 5.1 graphics cards, each capable of delivering up to 600W.
Is this power supply quiet during operation?
MSI states it's designed for low-noise operation with a Zero Fan Mode. However, one user reported the fan being audible even at idle in all three modes.
Is this PSU compatible with older graphics cards that use 8-pin PCIe connectors?
While it features dual 12V-2x6 connectors for newer cards, the Micro Center listing for a similar model (A1000G PCIE5) mentions 6 x 6+2-pin graphics connectors. You may need to verify the exact count for the A1000GS PCIE5 or use adapters for multiple older cards.
What does 'ATX 3.1 Ready' mean?
ATX 3.1 is a power supply standard that allows the PSU to handle higher power excursions (transient spikes) from components like modern GPUs, ensuring system stability.
What kind of capacitors does this power supply use?
It uses 100% server-grade 105°C Japanese capacitors, which are known for their durability and stable performance.
Buying Guide
When you're looking at a power supply like this, you need to think about what graphics card you're running now, and what you might run in the next few years. This unit is built for the newest stuff, especially those power-hungry NVIDIA cards with the 12V-2x6 connector. Also, consider your case size; a 150mm length is pretty standard but helps if you're tight on space.
Wattage (1000W)
This is how much power the supply can deliver to your components. 1000W is a lot, like a big engine in a car, and it's usually enough for high-end CPUs and the most powerful graphics cards, even with some overclocking headroom.
80+ Gold certification
This rating tells you how efficiently the power supply converts wall power into usable PC power. Gold means it's at least 87-90% efficient, which saves you a little on your electricity bill and means less wasted heat inside your case.
ATX 3.1 & PCIe 5.1 Ready with Dual 12V-2x6 Cables
This is crucial for modern, high-end graphics cards. ATX 3.1 handles sudden power spikes better, preventing system crashes, and the 12V-2x6 cables are the direct, high-power connectors for cards like the NVIDIA RTX 40 and upcoming 50 series, eliminating the need for bulky adapters.
Fully Modular
This means you only plug in the cables you actually need for your components. It's like having custom-length cables for everything, making your PC build much cleaner, improving airflow, and simplifying cable management.
Alternatives
If you need more traditional 8-pin PCIe connectors for multi-GPU setups or specific AMD cards, look for PSUs explicitly listing 4 or more native 6+2 pin connectors. If absolute silence is your top priority, research models with confirmed fanless modes under light loads or lower reported dB levels.
